REGULATOR FOR STEAM-HEATERS.

SPECIFICATION forming part of Letters Patent No. 363,470, dated May 24, 1887.

Application filed July 19, 1886.

To all whom it may concern:

Be it known that I, HOSEA K. KRIEBEL, of WVest Point, county of Montgomery, and State of Pennsylvania, have invented an Improvement in Regulators for Steam-Heaters, of

which the following is a specification.

My invention has reference to regulators for controlling the draft of steam or hot-water heaters for buildings; and it consists in certain improvements, all of which are fully set forth in the following specification, and shown in the accompanying drawing, which forms part thereof.

Automatic regulators have been used to control the draftdoor and chimney-damper to regulate the temperature of the fire and pressure of the steam, and this device has been worked by a suitable lever mechanism con-- trolled by a diaphragm actuated either by the steam or hot water in the boiler.

The object of my invention is to provide suitable means, in case of the rupture or destruction of the regulator-diaphragm, to antomatically and positively close the draft-door and chimney-damper or smother the fire, and thereby prevent danger, which would otherwise arise from an excessive generation of steam. I

In carrying out this invention I connect the draft-door and damper to the regulatinglever by means of unlatehing devices, which normally are looking, so that the said draftdoor and damper are operated by themovements of the regulating-lever; but in case of the rupture of the diaphragm-regulator these latches are tripped and the draft-door and damper will instantly close.

In the drawing is shown a sectional elevation through the regulating apparatus, and showing its connection with the draftdoor and damper.

A represents the body of the heater.

B is the regulator proper, and is formed into an upper compartment, b, and the lower compartment, 1), supported by a lever or flexible diaphragm, G. The lower compartment, 1), connects with the heater above or below the water-line by a pipe, a, it being equally'adapted to hot water or steam.

The diaphragmG in its movements reciprocates the rod D, which is connected to the regu- Serial No. 208,405.

latinglever E, and whereby the latter is oscillated. The lever E is pivoted at 6 close to the rod D. The rod D passes through an opening, d, in the top of the compartment b,

, and is provided with a valve-packing ring, F,

which is to prevent the escapeof steam or water in case of the rupture of the diaphragm O.

The lever E is weighted at E, so as to tend to depress the diaphragm.

G is the draft-door, and connects by a link, g,with the latch I, and pivoted to the lever E at i, and having the .hook support I, over which the link catches. This latch is held in operative position by a lock, J, which is operated by a flexible diaphragm, is, formed as a head to thepressure'chamber K. This pressure-chamber K connects by a flexible pipe, L, with the upper compartment, 1), of the regulator and is carried by the lever E, to which it is secured, as shown, in order that the rela tive positions of the pressure-chamber and lever may be maintained in all positions of the lever. The chimney-damper H is connected by a link, It, having an eye, Q, at the bottom, through which the bolt N passes to attach it to the other end of the lever E. This bolt N is carried by a frame, 0, made adjustable on the end of the lever E by set-screw P. This bolt is connected by a cord or wire with the latch I, so that when the said latch is tripped the bolt is withdrawn.

The operation is as follows: The apparatus being connected as shown and under normal operation, any variations in the temperature of the water or pressure by the steam will atfect the diaphragm O and,through the mediation of the rod D, oscillate the lever E to open or close the draft-doorG and damper H to automatically suit the requirements and prevent an excessive steam-pressure. If in time the diaphragm 0 becomes worn out or weakened and is ruptured, the steam or water will pass from the compartment 1) into the com partment b, and as the valve F is closed, due to the action of the weighted lever, the water or steam enters pipe L and acts upon the dia phragm 70. This actuates the lock J, causing it to free the latch I, whereupon the weight of the door G oscillates the said latch to free the link 9, and said oscillation of the latch withdraws the bolt N, simultaneously releasing the chimneydamper and causing it to close with the closing of the draft-door. The heater is then closed up and the fire becomes reduced in temperature,oris smothered out altogether.

It is evident that in place of the valve F being formed by a ring of packing material,

tion shown, it being possible to modify them in a large number of ways without departing from the spirit of the invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-
